Solution:
Upgrade to or install the attached PowerChute Business Edition upgrade (v9.2.1) & (9.0.4)which is shipped with JRE 8 Update 102. By upgrading to v9.2.1 or 9.0.4, the functional issues caused by the JRE 8 Update 91 changes are fixed. This upgrade is available for supported Windows and Linux operating systems.

Note: Once you have upgraded to v9.2.1, or 9.0.4 the software will be fully functional. However, if you then decide to upgrade the JRE to a later version than Update 102 using the JRE Configuration Tool, then the additional manual changes specified in Answer ID #FA264735, FA264736 & FA253763 are still required for communications between the PowerChute Agent and PowerChute Console.

If your UPS is a SU, SC, SUA, SURT, SURTA, Matrix PowerChute Agent 9.0.4 will be installed.
